Harrison woke up with a headache that felt like a drill boring into his temple.

The sunlight streaming through the floor-to-ceiling windows was offensive. He squinted, sitting up on the Italian leather sofa.

"Helena?" he croaked. "Where's the aspirin?"

Silence.

Then, the memory of the night before hit him. The flash. The ring in the champagne.

Sienna walked out of the kitchen. She was wearing one of Helena's silk robes. It was too tight across her chest.

"This coffee machine is impossible," she complained. "It has too many buttons."

Harrison rubbed his face. He walked to the hallway, needing to clear his head. He stopped in front of the mirror.

KEYS ON THE TABLE. The red lipstick looked like a wound across the glass.

Sienna came up behind him, wrapping her arms around his waist. "Good riddance. Now we have the place to ourselves."

Harrison pushed her away. He walked to the closet. It was half empty. But the expensive things-the things that signaled status-were all still there.

"She didn't take anything?" he muttered. He felt a surge of irritation. It was insulting. As if his money, the Vincent money, meant nothing to her.

He grabbed his phone and dialed his mother.

"She's lost her mind," he told Evelyn. "She threw the ring in a drink."

"Don't worry, darling," Evelyn's voice was crisp. "She's a nobody from nowhere. She needs the Vincent name. Give her seventy-two hours. Once she realizes she can't afford her rent, she'll come crawling back."

"Seventy-two hours," Harrison repeated. He liked the sound of that. It gave him a timeline. A deadline for her groveling.

Helena sat at an outdoor table at a bistro in Midtown. The wind was brisk, but the sun was warm.

She was eating spaghetti aglio e olio with double red pepper flakes. Harrison hated garlic. He hated spice. He said it was "peasant food."

It tasted like victory.

Her phone vibrated on the table. Harrison (5 missed calls).

She blocked the number.

"Hey," Whitney said, pointing her fork across the street. "That car has been there for ten minutes."

Helena looked up. Across the avenue, a black Maybach S680 was idling at the curb. The windows were tinted so dark they looked like ink.

A chill ran down Helena's spine. That wasn't a normal car. That was a tank disguised as luxury.

"Maybe it's Harrison," Whitney said nervously.

"Harrison drives a Porsche," Helena said. "He can't afford a Maybach. That car costs more than his annual allowance."

She wiped her mouth with a napkin. "I'm going to check."

"Helena, no!" Whitney hissed.

Helena stood up. She smoothed her trench coat and walked across the street. Her heels clicked rhythmically on the asphalt.

The car didn't move. The engine purred, a low, menacing rumble.

Helena stopped at the rear passenger window. She knocked on the glass.

For a long moment, nothing happened. Then, the window slid down just an inch.

She couldn't see a face. The interior was shadowed. But she saw eyes.

Dark grey. Cold. Intelligent.

She recognized them instantly. The man from the bathroom.

Her hand went to her pocket, but the cufflink wasn't there. It was in Whitney's junk drawer.

"Dr. Hensley," a voice came from the darkness. It was the same rasp, but stronger now. "We meet again."

Helena's heart hammered against her ribs. He knew her name.

"Are you following me?" Helena asked. She kept her voice steady, though her pulse was racing.

The rear door didn't open. Instead, the front passenger door swung out. A man stepped onto the sidewalk. He was huge, built like a linebacker in a suit that struggled to contain his shoulders.

He moved between Helena and the rear window, blocking her view of the grey eyes.

"The Principal wanted to ensure your safety, Dr. Hensley," the bodyguard said. His name was Lucas, though she didn't know it yet.

"I'm perfectly safe," Helena said, stepping back. "As long as you people stay away from me."

She looked past Lucas, trying to catch a glimpse of the man in the back. "Tell your boss I have his cufflink. I'll return it."

A low chuckle came from inside the car. It was amplified slightly, as if he were speaking near a microphone.

"Consider it a consultation fee, Doctor," the voice said.

"I don't accept payment from criminals," Helena snapped.

"Keep it," the voice commanded. The tone shifted, losing its amusement. "You'll need it."

Lucas pulled a card from his pocket. It was heavy, matte black stock. There was no name, just a number embossed in silver.

"If you have trouble," Lucas said, pressing it into her hand. "Call."

He turned and got back into the car. The window rolled up, sealing the grey eyes away. The Maybach pulled into traffic, moving with the aggressive grace of a shark in water.

Helena looked down at the card. She felt a mix of anger and fear. She walked back to the table and ripped the card in half, dropping the pieces into the ashtray.

"Who was it?" Whitney asked, eyes wide. "Mafia?"

"Just an arrogant jerk," Helena said.

Inside the Maybach, Collis Vincent winced as the car hit a pothole. He pressed a hand to his side. The makeshift bandage held, but the ache was a constant, throbbing reminder.

He picked up a manila folder from the seat next to him. It was labeled HENSLEY, HELENA.

He flipped it open. Her dissertation on tracking illicit funds through fine art sales. Copies of her bank statements. Her dual degree transcript from Columbia-Art History and Forensic Accounting, both summa cum laude.

"She's Harrison's fiancée, sir," Lucas said from the front seat, glancing in the rearview mirror.

"Ex-fiancée," Collis corrected. He ran a finger over a photo of Helena. She wasn't smiling in the picture. She looked formidable. "She moved out last night."

"Harrison is a fool," Lucas muttered.

"Harrison is a child," Collis said. "He doesn't know what he had."

"Do we need to neutralize her?" Lucas asked. "She saw you bleeding. She knows you were compromised."

Collis closed the folder. "No."

He remembered the way her hands had moved in the dark. Steady. Precise. She hadn't panicked. She had staunched the bleeding with a strip of her dress and told him to shut up.

"She is a perfect asset," Collis said softly. "Keep the injury quiet. Especially from the estate."

"Yes, sir."

Collis looked out the window. He felt a strange sensation in his chest. It wasn't pain. It was the thrill of the hunt.

Helena returned to her new apartment that evening, exhausted. She had a major auction preview scheduled for the morning, and she needed sleep.

As she unlocked the door, her foot hit something on the floor.

A box. Wrapped in dark blue paper.

She frowned. She hadn't ordered anything. Whitney was out.

She picked it up and carried it to the kitchen table. She tore off the paper.

It was a wooden case, polished mahogany. She opened the lid.

Inside, nestled in black velvet, lay a set of exquisitely crafted antique tools-slim, elegant, and deadly precise. There were fine-bladed knives, curved slicers, and slender awls, their steel gleaming under the kitchen light.

Helena recognized them immediately. They were 19th-century bookkeeping knives, once used by forensic auditors of a bygone era to slice through the wax seals and stitched bindings of fraudulent ledgers-to literally "dissect" the books. The set was a collector's piece, a darkly beautiful fusion of her two obsessions: art history and the anatomy of financial crime.

On the handle of the main knife, her initials were engraved: H.H.

There was no card.

Helena stared at the knives. They were beautiful. Deadly. And incredibly expensive.

He knew where she lived. He knew what she really did. And he knew exactly how to speak to the part of her that saw financial fraud as a body to be autopsied, a puzzle to be taken apart piece by piece.

It was terrifying.

Harrison Vincent stood in the middle of his living room, looking at a pile of wet towels on the floor.

"Helena!" he shouted. "Where is the blue folder? The trust documents!"

Silence answered him.

Then, Sienna walked in. She was eating a slice of pizza from a box sitting on the coffee table.

"Stop yelling," she said, chewing loudly. "That old hag wouldn't listen to me, so I fired her."

Harrison froze. "You fired Mrs. Higgins?"

"She corrected my pronunciation of 'Givenchy'," Sienna rolled her eyes. "She was rude."

"Mrs. Higgins has been with the family for thirty years!" Harrison exploded. "She runs this house! She knows where everything is!"

He looked around. The apartment, usually a sanctuary of minimalist grey and white, was cluttered with Sienna's shopping bags. She had replaced the abstract art over the fireplace with a gaudy, pink oil painting of a poodle.

"It's kitsch, babe," Sienna had said. "It's artistic."

Harrison felt a vein throb in his forehead. He walked to the kitchen to get water. He tripped over a pair of Sienna's heels left in the hallway.

He caught himself on the counter, knocking over a glass of red wine Sienna had left there. The wine splashed across the marble and dripped onto the floor.

"Oh my god," Sienna whined. "You're so clumsy."

She grabbed a dishtowel-a decorative silk one-and started smearing the wine around, making it worse.

"Get out," Harrison said.

"What?"

"Get out of the kitchen! Don't touch anything!"

Sienna threw the towel down and stormed off to the bedroom, slamming the door.

Harrison stood in the mess. He missed the quiet. He missed the way the house always smelled of fresh linen and Helena's subtle tuberose perfume. He missed the way his life just worked when she was around.

He pulled out his phone. He typed a text: Okay, you made your point. The house is a mess. Come back and fix it.

Message Send Failure.

He stared at the screen. She had blocked him.

Helena sat in her tiny kitchen in Brooklyn. She was using the new antique knife-sterilized, of course-to slice an apple. The blade went through the fruit like it was butter.

Her phone pinged. A notification from her bank: Supplementary Card Ending in 4098 - Access Denied.

Harrison was trying to cut her off.

She smiled. She had cut that card up with kitchen shears two days ago.

She opened her laptop to check the Sotheby's auction schedule. A news alert popped up in the corner of the screen.

VINCENT GROUP SHARES WOBBLE AS CEO COLLIS VINCENT MISSES BOARD MEETING. RUMORS, LIKELY FUELED BY RIVAL FIRM DOUGLAS MARKS, OF ILLNESS CIRCULATE.

There was a photo of a man getting into a car. It was blurry, taken from a distance.

Helena leaned in. The build of the man... the broad shoulders, the way he held himself. It looked familiar.

She shook her head. It couldn't be. Collis Vincent was a myth, the ruthless uncle Harrison was terrified of. The man in the bathroom was just a high-level criminal.

She closed the tab. She had a collection to appraise tomorrow.
